TINNERS FIRE-POT.

SPECIFICATION forming part of Letters Patent N 0. 640,914, dated January9, 1900.

Application filed April 19,1899. Serial No. 713,622. (No model.)

To all whom it may concern:

Be it known that I, JOHN S. HULL, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Fire-Pots; and I do hereby declare thefollowing to be a full, clear, and exact description of the inven tion,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to fire-pots such as are generally used by tinners,plumbers, and miners, or by assayers in their laboratories, has for itsobject the furnishing of a device which can be used for a variety ofpurposes, and consists in certain improvements of construction whichwill be fully disclosed in the following specification and claims.

In the accompanying drawings, which form part of this specification,Figure 1 represents a vertical section, partly in side elevation; Fig.2, a vertical transverse section of the firepot; Fig. 3, a horizontalsection on the line as as, Fig. 2; Fig. 4, a plan view of the top ring,

and Fig. 5 a detail vertical section of the firepot.

Reference being had to the drawings and the letters thereon, A indicatesa reservoir for hydrocarbon oil having a filling-top B, which isdetachably connected to a bushing a for removal to supply gasolene orother hydrocarbon liquid to the reservoir, a branch I) for connectingwith an air-pump to charge the reservoir with air under pressure, and avalve 0 for cutting off the supply of air. A Well 0 in the bottom of thereservoir, from which extends a screw-threaded pipe d, having an elbow eat its outer end, to which is attached a feeding-chamber f and intowhich extends an extern ally-screw-threaded tube g, packed by a glandit, supports a hydrocarbonburner D, so that it may be adjusted laterallyand vertically to suit any use to which it may be applied.

E indicates a fire-pot made in two vertical sections connected by bolts(not shown) extending through lugs i, and one of the sections isprovided with an extension it, having an opening Z, through whichsoldering-irons or other articles to be heated are inserted, and theopening may be closed when heating a melting-pot F or other deviceplaced in or on top of the fire-pot. The door it is secured to the lugsm by hinges n, with a rod 0 extending through them, and on the hingesare formed seats or extensions 19, which engage the under side of theextension 7c and sustain the door in an approximately horizontalposition, as shown in Fig. 5, to support the article inserted throughthe opening Z to be heated, and opposite the extension is an ex tension70 to support the ends of the soldering irons and is usually providedwith a slab of soapstone to protect the irons.

In the bottom of the fire-pot is secured a transverse bar or guide g, onwhich slides a deflector G, adjusted by a rod r and moved in under thepot F to direct the heat against it and prevent the flame from theburner being wasted.

H is the top ring, secured to the fire-pot and extending inwardly fromthe perimeter thereof,being provided with a central openingsand lugs t,and upon the upper surface of the ring are vertical projections 10 tosupport a pan, flat-bottom kettle, or other utensil of greater diameterthan the opening 5 in the ring to allow the hot gases to escape from thefire-pot.

I is a nozzle to receive the burner D, which projects or extends intothe fire-pot, and to admit of the burner being swung out of the fire-potto be used for other purposes one section 1; of the nozzle is secured tothe fire-pot by hinges w to swing laterally, as shown in Fig.

The melting pot F is provided with an outwardlyextending bead or rim y,upon which the pot rests on the top ring H in its lowest position in thefire-pot,and on the outer surface of the melting-pot, below the head 3are lateral projections z z of different lengths to engage the lugs t onthe top ring and raise the melting-pot, as may be required.

Near the upper end of the firepot are ports or apertures K for the bail.(Not shown.)

The fire-pot rests upon and is secured to a perforated cooling-chamber Lto prevent the heat of the fire-pot being transmitted to theliquid-reservoir A and its contents, and this chamber forms a convenienthandle for using the burner as a paint-breamer. The chamber L is securedto the reservoir A by a flange a and a bolt or pin b, passing throughthem, and by a rod 0', extending through the bottom of the reservoir andconnected at its upper end to the bolt 1), and a bolt d connects thefire-pot to the upper end of the coolingchamber.

Having thus fully described my invention, what I claim is 1. A fire-pothaving an opening to receive soldering-irons, a door controlling saidopen: ing and provided with hinges constructed to engage the fire-potand support the door in an approximately horizontal position, and anozzle having a separate section hinged to the pot to swing laterally;in combination with a laterally-adjustable hydrocarbon-burner.

2. A fire-pot having an opening to receive soldering-irons, and a nozzlehaving a separate section hinged to the pot to swing laterally thereon;in combination with a laterallyadjustable hydrocarbon-burner.

3. A fire-pot provided with an opening for soldering-irons, a doorcontrolling said opening, a transverseguide at its bottom, an opening toreceive a hydrocarbon-burner, and a deflector opposite said opening andlaterally movable on said guide; in combination with a melting-pot, anda hydrocarbon-burner;

4. A fire-pot having an opening for soldering-irons, an opening toreceive a hydrocarbon-burner, and a top ring provided withinwardly-extending lugs; in combination with a hydrocarbon-burner, and amelting-pot having means on its outer surface to engage the lug on saidtop ring and suspend the melting pot in the fire-pot.

5. A fire-pot having an opening for soldering-irons, a door controllingsaid opening, a nozzle to receive a hydrocarbon-burner provided with aseparate section hinged to the pot to swing laterally; in combinationwith a hydrocarbon-burner projecting into said nozzle, and a reservoiron which the fire-pot is supported and to which the burner is connectedto swing laterally in and out of said nozzle.

6. A fire-pot having an opening for solder.- ing-irons, a nozzle havinga hinged section, a hydrocarbon-reservoir having a perforatedair-chamber connected thereto and the firepot detachably secured to theair-chamber; in combination with a hydrocarbon-burner connected to thereservoir and vertically and laterally adjustable thereon.

In testimony whereof I atfix my signature in presence of two witnesses.
